Hair Follicle Drug Testing - Evanston, IL

What it is, How it works

Hair testing is widely regarded as an effective method for identifying drug and alcohol consumption. Hair captures a lengthy history of alcohol and drugs by sealing biomarkers in the fibers of the emerging hair strand. When taken from near the scalp, hair offers up to roughly a 3-month detection timeframe for alcohol and other substances. Collecting hair is straightforward, relatively tamper-resistant, and straightforward to transport.

A 1.5-inch segment of around 200 hairs (equivalent to the size of a #2 pencil) next to the scalp will yield 100mg of hair, which is the optimal sample for analysis and verification. For EtG, additional tests, and/or those exceeding 10 panels, it is advised to gather 150mg of the sample. It is recommended to measure the sample on a jeweler’s scale. In the absence of scalp hair, an equal volume of body hair can be used. References to head hair pertain solely to scalp hair. Body hair covers all other types of hair (facial, axillary, etc.).

Process Overview

The principal steps in the laboratory assessment of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into a laboratory’s system. This process includes verifying proper sealing and shipment of the sample, allocation of a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid test for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug use in most samples, a positive result necessitates validation to be allowable in court. Samples that yield a presumptive positive in Screening require secondary confirmation.

In cases where a sample shows a presumptive positive at the Screening stage, more hair is drawn from the initial sample and readied for Extraction. During this step, drugs are removed from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug testing the most intricate procedure to execute.

Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positive results are cleansed before confirmation as required. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter time frame.
• Challenging to deceive: Cheating a hair drug test is extremely tough, thereby enhancing result accuracy.
• Yields historical data: It can determine a pattern of drug usage over time, not just immediate usage.

Limitations:

• Inability to detect recent use: It generally takes around 5-7 days for drugs to be discernible in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although frequently called "hair follicle tests", the analysis is conducted on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Evanston, IL centers on superior detection accuracy and reliability. Hair tests present a broader detection timeframe compared to urine tests which are effective primarily in detecting recent drug use. Moreover, hair follicle testing minimizes the risk of false negatives, granting more confidence in the results.

Through hair analysis, substances are detectable long after consumption, whereas urine tests miss past instances if the system has cleared them. This makes hair testing an ideal choice for thorough screening, particularly where substance abuse policies are stringent.
